These tables list the recruitable NPCs who are your potential party members in BG1 and BG2. Both tables are spoiler-friendly: The only text currently visible shows each NPC's Class (and kit, if applicable), Alignment, and starting location, so that if you're looking for, say, an Evil-aligned Thief, you know where to go. All other data can only be revealed by clicking & dragging through the invisible text.
          For each game, I've listed the NPCs in roughly the order you will be able to recruit them into your party: Don't make plans for a character waaaaay down the list, unless you know you can actually get that character relatively quickly. The ToB NPC becomes accessible almost immediately after the first fight of ToB.
          The NPCs may be slightly different in different games: Their level, hitpoints, equipment, and weapon proficiencies may change a bit. That's because there are multiple versions of each NPC: At the moment each character joins your party, the game checks the list of "incarnations" of that NPC, and picks the one that most closely matches the PC's EXP level. This ensures a more balanced game, so you don't have a Level 7 PC directing a band of Level 3 characters, or vice versa.
          This page does not list the 5 NPCs available only during the training session with Obe in BG1. They can in fact be brought out into the rest of the game, but that was clearly never intended to be possible.
